Introduction

1.1 Introduction to the H-2191 and H-2192

Both the H-2191 and H-2192 are modem based communication devices. The main difference is
the H-2191 is based on a standard land line connection while the H-2192 uses a cell phone based
modem for communications.

NOTE: Items discussed in this manual that apply to both the H-2191 and to the H-2192 will be
listed as H-219X. Subjects that pertain only to one unit or the other will use the appropriate
model number.

The H-219X data/voice modems operate in a fashion similar to many other modems, but they
also have been designed with special features that make them ideal for remote applications in the
data logging industry. While in a sleep mode, the H-219X draws very little power making them
ideal for battery operation. The advanced setup options are easily programmed through the serial
port or remotely via a data connection. The H-219X operate in several different modes.

Voice Call In Over Land Line or Cell Phone:
When called, the H-2191 will answer in a voice mode and later switch to a data mode if
necessary. The H-2192 acts the same as the H-2191 except it will not enter a data mode. The
voice mode allows the user to retrieve data by simply calling the H-219X from any touch tone
phone. Data for the voice mode normally comes form a WATE RLOG series data logger.

®

Voice Call Out (ALARM) Over Land Line or Cell Phone:
The H-219X can also call out in a voice mode when an alarm condition exists.

Voice Over RF Radio Link:
This is the same as the land line or cell phone operation except the alarm call out option is not
supported. To call a site, instead of a phone number, a 2 to 4 digit code pressed on a keypad of
the calling radio is used.

Data Over Land Line Connection:
In the data mode, the H-2191 may be used to program or retrieve data from any WATERLOG
series data logger through the serial port. The connection is made using a terminal emulation
program such as Hyper Term running on a PC with a standard modem.

Data Over Cell Phone:
In the data mode, the H-2192 may be used to program or retrieve data from any WATERLOG
To access the data logger using the cell phone modem a TCP/IP connection must be used. This
can also be done using the Hyper Term program.

®

H-219X Introduction 1-1

Text Message Call In Using The Cell Phone:
The H-2192 can also send data in a text message. To receive a text message with the data simply
send a text message to the H-2192. The H-2192 will reply to the calling number with the current
data.

Text Message Call Out (Alarm) Using The Cell Phone:
The H-2192 can also send data in a text message based on some alarm condition. When an alarm
condition occurs, the H-2192 will send a text message to selected recipients unsolicited.

1.5 H-2192 SIM Card Installation

Before the H-2192 GSM cell phone modem can be used a SIM card must be obtained and
activated by a local provider, then installed in the modem.

Use the following steps to install the SIM card.

1 - Remove the two screws on the end of the case with the LED’s and ground lug.

2 - Disconnect the ground lug from the end plate by pulling gently on the connector on the
ground wire. Be careful not to bend the end plate. Also be careful not to pull the end plate away
from the case to the point the antenna wire disconnects or is stressed.

3 - Holding the other end plate in one hand, gently pull the top half of the case away from the end
plate exposing the PC board inside. With the top of the case slid back about half way the modem
module will be exposed.

4 - At one end of the modem module will be a socket for the SIM card. Properly orient the SIM
card to the socket and insert it into the socket.

5 - Push the top of the case back into its normal position.

6 - Reconnect the ground lug wire to the end plate.

7 - align the end plate and replace the two screws.

Note: If the antenna cable did become disconnected from the modem module, then simply
reconnect it. Be careful as this is a small connector and does not take a lot of pressure to
reconnect it.

1.6 FCC Approval

Type of Service: The H-2191 is designed to be used on a standard device telephone line. It

connects to the telephone line by means of a standard jack called the USOC RJ-11C. Connection
to telephone company provided coin service (central office implemented systems) is prohibited.

Connection to party line service is subject to state tariffs.

Telephone Company Procedures: The goal of the telephone company is to provide the best
service possible. In order to do this, it may occasionally be necessary for them to make changes
in their equipment, operations, or procedures. If these changes affect your service or the
operation of your equipment, the telephone company will give you a written notice in order to
allow you to make any changes necessary to maintain uninterrupted service.

In certain circumstances, it may be necessary for the telephone company to request information

1-4 Introduction H-219X

from you concerning the equipment which you have connected to your telephone line. Upon
request of the telephone company, provide the FCC registration number and the ringer
equivalence number (REN); both of these items are listed on the equipment label. The sum of all
the REN’s on your telephone line should be less than five in order to assure proper service from
the telephone company. In some cases, a sum of five may not be useable on a given line.

If Problems Arise: If any of your telephone equipment is not operating properly, and you expect
it may be affecting the telephone line, immediately remove it from the telephone line to prevent
harm to the telephone network. If the telephone company notes a problem, they may temporarily
discontinue service. When practical, they will notify you in advance of this disconnection. If
advanced notice is not feasible, you will be notified as soon as possible. When you are notified,
you will be given the opportunity to correct the problem and be informed of your right to file a
complaint with the FCC. Contact your telephone company if you have any questions about your
telephone line. In the event any repairs are required on the H-2191, they should be performed
only by Design Analysis Associates. In this event call Design Analysis Associates for assistance.

2.2.1 Phone Connection

The phone connection is a standard RJ11 connector allowing a simple connection to a phone
system.

2.2.2 Cell Phone Antenna Connection

The H-2192 uses a built in cell phone that uses this connection for its antenna.

2.2.3 RF Radio Connection

This connection was designed to plug directly into a Data Radio DL-3400 RF radio using a
straight through cable. This connection handles the audio in and out, the push to talk (PPT)
function, and other control signals. The H-219X also controls the power to the radio so it can be
turned off to save power.

2.2.4 Earth Ground Connection

There is a connection for an earth ground. It is very important that an earth ground be provided
and connected to this grounding post on the H-219X. Other equipment in the system should also
be connected to an earth ground.

H-219X Installation 2-3

2.4 LED Descriptions

DTR LED:

The DTR LED indicates the data logger connected to RS-232 port is active. This LED will be on
any time the data logger is sending data to the modem, any time the modem requests data from
the data logger, and when a data connection is active.

Modem Pwr:

On the H-2191, the modem is normally turned off and the unit is in a low power mode.
Incoming calls will be detected and wake up the modem. Once the modem is awake the call can
be answered.

On the H-2192 the modem power must be on to receive a call. For the H-2192 the power can be
programmed to turn on and off and set times or based on a battery voltage, or on always.

DCD LED

This is the Data Carrier Detect signal form the modem used in the H-2191. When a data
connection is valid this LED turns on.

Link LED:

When using the H-2192 this LED indicates the status of the cell phone connection. This LED is
off if the internal modem module is powered off. This LED is on solid if the modem power is on
and the cell modem is not registered on the network. This normally only happens for a few
seconds when the modem module is first powered up. This LED will blink at a rate of once
every 2 to 3 seconds when it is registered on the network and ready for operation. If a call is
active then this LED blinks at a faster rate of about 1 a second.

DL3400 Radio Pwr LED:

The VHF or UHF radio must be powered for operation. This LED indicated the status of the
power supplied to the radio.

NOTE: The Ethernet connector has a couple of LED’s on it also, but it is not activated at this
time.

The following paragraphs give a basic outline of the installation process. Your installation may
vary according to your intended application and site conditions.

! Choose the best place to mount the equipment. Wiring should be kept as short as

possible. Equipment with displays and keyboards should be easily accessible. Equipment
with exposed wiring terminals should be mounted with the terminals toward the bottom
of the case. Antenna cables should be kept short. Also consider any future expansion,
function of the equipment, vandalism, etc.

! Physically mount all the equipment in the desired locations.

! Connect a power source to the H-219X. This power source should be a 12 Volt power

source, but not to exceed 16 Volts. Use 18 gauge wires or heavier for a standard modem
application, if the RF radio is used then use 16 gauge or larger wires for the power .

! Connect the phone line to the phone line connection of the H-2191 using a standard RJ11

connector. For the H-2192, cell phone sites, install and connect the antenna.

! For sites using the RF radio, install the radio and make appropriate connections as

H-219X Installation 2-5

needed. This includes the data / power cable, and antennas.

! On sites using the H-2192 cell phone and an RF radio, install the antennas and cables to

prevent the two from interfering with each other.

! Connect the RS-232 cable to the XL series data logger or other equipment. When

connected to the XL series data logger a straight through cable should be used, a NULL
modem adaptor is not required.

! Evaluate the earth grounding of all the equipment at the site and make sure the modem is

included in this grounding scheme. An earth ground connector has been provided for this
purpose.

2.6 Testing the Installation

The H-219X is designed to be a plug and play device. Once connected, it should function without
any additional setup in the data mode and only a few settings for the voice mode. Normally the
voice mode settings of the H-219X will be setup in the office, but they may also be done in the
field. This includes adding the voice messages and any settings for the stand alone mode. See the
next chapter for details on the voice mode setups.

Before leaving a site, make sure the equipment is functioning properly. The best way to confirm
that the H-219X is connected properly and operating properly is to call it. The voice mode is the
easiest to test. If a cell phone is available, call the H-219X and the voice sign on message should
be heard. Run through the different options to verify that they are all working correctly. A
common problem is that the messages do not match the data, for example the first message may
refer to stage when the data reported is temperature. Either change the messages to correspond to
the data or rearrange the order of the data being sent to the H-219X.

To test the data mode, it is again best to call the site and verify the connection and operation.
When used with an XL series data logger, pressing the enter key a few times should produce the
arrow prompt used by the command mode of the data logger or a menu will be displayed. If the
command prompt is displayed then standard commands for the XL series logger may be used. If
the menu is displayed then the menu may be accessed as usual.

It may also be helpful to hook a current meter to the H-2191 and monitor the power consumption
of the H-2191 in its sleep mode, voice mode, and data mode. See the specifications for the actual
levels.

Operation

3.1 Overview

The H-219X is easy to set up and operate, and can be used as a regular data modem as well as a
voice modem. The modem uses the standard AT and S register commands, however in most
cases they are handled automatically so the user does not need to know anything about them.
Options related to the voice mode of the H-219X are programmed using a built in menu or from
an extended set of commands.

3.2 Data Mode Operation Over Standard Phone System

The main purpose of the H-2191 in the data mode is to allow data communications between a PC
and a remote WATERLOG series data logger. This allows for remote data transfers, and for
changes to the data logger setups remotely. If the H-219-1 is operated with a WATERLOG series
data logger, all that needs to be done is to connect the power, the RS-232 cable, and the phone
line to the H-2191.

Although this may seem too simple, the system is designed to be a plug and play system,
meaning that only a few steps are necessary for operation. If you are going to use the modem
with something other than a WATERLOG series data logger, standard AT commands and S
registers may be changed for special modes if needed. In most cases no changes are needed.

When used in the data mode only, no setup changes are required on the data logger. This is the
simplest mode of operation.

Note: The H-2191 is configured to always answer in the voice mode. When the H-2191 is

called it first looks for a keyed response from a touch-tone phone in order to continue
with the menu for voice capability. If it does not receive a keyed response within five
seconds, the H-2191 will automatically switch to the data mode and expect to
communicate with another modem in a data mode.

3.3 Voice Call In Over Standard Phone System

Before proceeding, an explanation of how and what data will be sent from the data logger to the
H-2191 modem may be helpful.

3.3.1 Voice Call In Overview

When a incoming call is made to get data from a site in a voice mode, the data spoken is data that
resides in the modem, not the logger. On the XL series of loggers, there is a special menu option
to define what data will be sent to the modem and the order in which it will be sent. This data is

H-219X Operation 3-1

normally sent to the modem each time the logger scans the different sensors. For example if the
logger is set to scan the sensors every 15 minutes, then data is normally sent to the modem every
15 minutes. For more instructions on this feature, please see the corresponding section in the XL
Series data logger owner’s manual.

The data coming from the data logger will be stored in memory locations referred to as data value
boxes within the H-219X. There are ten data value boxes labeled BOX01 to BOX10. As data is
sent from the data logger to the modem it is placed in data box01 and continues until no more
data is sent or all the data boxes are full. A time stamp is also sent to the modem so the time the
data value was measured is known. The following table gives a simple visual representation of
how data is stored in the modem.

Time Stamp Box 01 Box 02 Box 03 - - - Box 10

Each data box has a user programable message that will be spoken to identify the data when a
voice call is made. A typical message would look like the following:

“The battery voltage is $v01 volts”

Notice the ‘$’ character in the message. The ‘$’ is used by the system to perform some task at
that point. The character just after the ‘$’ indicates the action to take. In this case the next
character is a ‘v’ which stands for ‘data value’. So in the above message the $v01 means insert
the value from data box 01 into the message when it is spoken.

For example, if the value in box01 is 34.25 and the user programmed the message for box01 to
“The stage is $v01 feet” then the unit would speak “The stage is 34.25 feet", and then move on to
the next data value if it is valid.

Now besides there being 10 different data boxes like a columns a table, there are also multiple
rows to hold older data.

Currently, this is a 10 by 13 table used to hold the data values. This is basically 10 values wide
for the different types of data and 12 values deep for historical data. One extra row of data for
non scheduled updates.
